PIPE-DRESSING TOOL.

Specification of Letters Patent.

Patented Feb. 13, 1906 Application filed December 31, 1904:. Serial No-239,249.

To aZZ whom t't may concern:

Be it known that I, WILLIAM RrrsoHARD, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented a new and useful Pipe-Dressing Tool, of which thefollowing is a specification.

The present invention relates more particularly to means for taperingthe ends of lead pipes in making joints, though perhaps useful for otheranalogous purposes.

One of the princlpal objects is to provide a simple implement of a novelnature by means of which the end of a pipe can be accurately andconcentrically tapered, and such tapered end will have a smooth surfacein order that a successful joint may be obtained, the implement being,furthermore, so constructed that it may be successfully employed onpipes of different sizes.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a view in elevation of thesame. Fig. 2 is a longitudinal sectional view therethrough. Fig. 3 is across sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a detailperspective view of the stem-bushing, and Fig. 5 is a detail perspectiveview of the knife-blade.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated a tapering body 6 is employed, having atone end a longitudinally-disposed neck 7, which carries atransversely-disposed handle-bar 8. The body 6 is provided with atapering work-receiving socket 9, having its outer end opening from theend of the body opposite the neck 7 and handle 8. Projecting from theinner end of the socket 9 longitudinally of the tool and concentric tothe convergent side walls of said socket is a journal-stem, which in thepresent instance is shown as comprising a core 10, having detachablymounted thereon a bushing 11, said bushing having an end wall 12,fitting upon the end of the core 10 and having a screw 13 passingtherethrough and threaded into the end of said core. The inner end ofthe bushing is provided with a key-lug 14, which detachably engages in akey-seat 15, formed in the workreceiving-socket wall 9.

One of the outer Walls of the body 6 is provided with an enlargement 16,and formed is adjustable in its seat and is adapted to be moved by meansof adjusting-screws 21, threaded through the rear walls of said seat andbearing against the rear side of the blade. Said blade is furthermoreprovided with transversely-disposed slots 22, through which are passedholding-screws 23, threaded into the bottom of the seat, or, in otherwords, into the wall of the body.

In using the device the journal-stem is inserted into the end of thepipe to be tapered. If the bore of said pipe is small, the bushing isremoved, and for pipes of larger bores the bushing shown or one oflarger diameter may be employed. It will thus be clear that the toolWlll be centered upon the pipe and that upon turning said tool andholding the pipe against movement, or vice versa, the blade will cut thematerial from the end and properly bevel the same. Said blade may beadjusted, if desired, and held in different relative positions withrespect to the stem. Furthermore, it may be readily removed should itbecome desirable or necessary. It will thus be seen that a simpleinstrument is provided by means of which pipes or other hollow work canbe neatly and properly dressed in order to secure efiective joints.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose-skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construc tion may be resorted to without departing fromthe s irit or sacrificing any of the advantages o the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an implement of the class described, a body, a journal-stemcarried thereby and comprising a core, a bushing mounted on the core, ascrew connecting the outer ends of the core and bushing to hold the sameagainst relative longitudinal movement, the. body and bushing beingprovided, one With a key- 2. In an implement of the class described,

a body having a tapering Work-receiving socket, a journal-stem extendingcentrally Within the socket, saidbody having a recessed key-seat at theinner end of the socket at one side of the base of the core, a cuttercarried by'the body and projecting into the socket, a bushing detachablyfitted upon the core and having a lateral outstanding key at its innerend that fits in the socket and holds the bushing against rotation onthe core, and a retaining-screw passed through the outer end of thebushing and threaded longitudinally into the free end of the core.

In testimony that I claim the foregoing as my own I have hereto afiiXedmy signature in the presence of two Witnesses.

WILLIAM RITSOHARD.
